RZ/RD 350 & Misc. 2-Stroke Tech BBS

nice ..............ive never had luck with different air filters i always leave stock boxes , good results with little testing with jetting on other page but now have a big range of jets and jjh needles will try over the next few days

we have 4 weeeks off work , total country lock down

anyone done any more testing as of late ??

i still have not painted my bike or ridden it :)
but i have primed the parts and might even put the tank on and try out some of these jetting tips

with all this covid virus stuff going on

the Oceana Rd400 was never sold under the daytona name
they were just Rd400f and Rd400g

ktm free ride 250 uses them aswell , if that makes it easier
did for me !

i have 5/8 and 14mm fitted with brembo 4 pots and fzr 4 pots
dont like the 5/8 as it has little feel the 14mm is much better

i would go with a 14mm master with the 2 piston calipers

genuine nissin is the best way to go 11mm will give you softer lever and more feel . but require more travel to get the pressure https://japan.webike.net/products/21554403.html 13mm will be more pressure at the lever less feel and less travel https://japan.webike.net/products/1448221.html depends wh...

need to keep this post alive ! anyone else been plying with the pwks this year ? ive moved on to a TDR250 and other things while my 350 is wating for paint but i was happy with the testing i did before i pulled the bike down in the mean time ive bought jjh needles and a good choice of jets just look...

vertex are cast but are 12-21% silicon , really well known in the off road world , next rebuild i do on a 350 i will be using vertex , they are a really high quality piston have mitaka (prox tkrj) in 6 bikes now and no problems they are a very good piston aswell i would stay away from forged its not...

Local bike shops want $16 per jet !! people want $50 us$ to send a small selections of jets across the world so finding them at a decent price and good postage is hard i do have some pilots and mains coming , will get some needles next time i need dirt bike bits , ktm freeride 250 uses 28s with j se...

Was just testing and running what i had and could get my hands on . I didnt want to spend few hundred $$ in jets and not need them Went for another ride and its close , just miss matched mains dont help 45 is very good i cant fault it down low needle feels good aswell guys in japan are running from ...

Ive just been sorting out my pwk setup over the last week few bits to fiddle around with , throttle cable is putting pressure on one carb causing it to open so need to fix that but i went for the first ride today stock 31k engine , pipes ,banshee reeds , full stock airbox , oil injection ,zeel but s...

just reading through old threads on jetting

trying to gauge on what to use on a fairly stock bike with pipes and a zeel , stock airbox etc

There is one little section under the yamaha decal on the tail that i can get a reading off
I will remove the goo and give it a polish tomorrow and see what code comes back.

Just getting my japanese 350RR ready for paint . I have removed the decals on the seat panels to reveal a nice fresh section of the pearl white (silky white). I work at a paint shop so i gave the panel a good polish and scanned the section with the spectro machine . We use cromax paint system which ...
